We must make the fractions have common denominators, which in this case is 15.
-4 / 5 = -12 / 15
So, -4/5 + 7/15 can be rewritten as
-12 / 15 + 7 / 15 and the answer is:
-5 / 15 which equals
-1 / 3
First, we turn the denominators into 15, like this:
[tex] \frac{-12}{15} + \frac{7}{15} [/tex]
And we get [tex] \frac{-5}{15} [/tex].
Then we just simplify, and the answer is: -1/3
